OGSA-DAI version 4

Version: 
4.0

Features:
* OGSA-DAI SQL views components, previously released in December 2008, have now been refactored and fully-integrated. SQL views now use many of the same SQL parsing components as DQP.
* Generic activities contributed by the ADMIRE project. These prototype activities allow you to do joins or transform a stream of tuples using a scripting language such as JavaScript.

A WS-DAI implementation using OGSA-DAI: Challenges and experiences

Speaker(s): 
Presentation Type: 
poster

OGSA-DAI provides an extensible framework that allows data resources to be incorporated into distributed systems. The WS-DAI (Web Service Data Access and Integration) family of specifications defines web service interfaces to data resources, such as relational or XML databases. Providing reference implementations for such specifications is important for the improvement of the specifications and the satisfaction of the interoperability goal.

OGSA-DAI 3.1 SQL views extension pack 1.0 released

Version: 
3.1

The OGSA-DAI project, a partner in OMII-UK, in collaboration with BEinGRID (http://www.beingrid.eu), have released the OGSA-DAI 3.1 SQL views extension pack 1.0. This is a proof-of-concept of an implementation of SQL views in OGSA-DAI 3.1 which allows SQL views to be defined over read-only relational databases. It also provides a layer in which the users Grid credentials can be used to determine the information presented in the view. This is part of OGSA-DAI's ongoing work to support more powerful data access, control and management scenarios.

Open Grid Services Architecture Data Access and Integration

The huge increase in the volume of data produced in research and business environments in the last decade has been likened to a "data explosion". Not only is this data volumes on a massive scale, it is also heterogeneous and dynamic and in many cases needs to be shared across both organisational and geographical boundaries. Accordingly, data management is increasingly challenging to both research and business organisations alike.
